Gary,
If you turn the VCR (in VCR mode) to channel 11, do you get a picture?
If so, this does not make sense.
If you can change channels by the channel up/dn buttons, on the VCR and see the
channels change, it should also record OK.
This is the steps I go through with customers, when they tell me they get snow
on
playback.
If it is still not recording,then I really don't know what to tell you, but the
TV/VCR indicator in the display has nothing to do with what channel the VCR is
receiving.
My guess is maybe you are going to the wrong part of the tape to view what you
recorded.
Be sure you are at the beginning of the tape.
I know most of this sounds trivial, but by your description...this just does not
make sense.
So...check channels coming through VCR.
Check VHS tape, be sure you playback the same section your recorded.
Good luck.

Ok, I'll try to explain again.
The VCR does not record the channel I pre-program it to record, but
rather just snow shows up on playback (and no sound). I have only tried
channels 13 or below so it is not a CATV/antenna setting problem. When I
record manually, it records the channel I have the VCR set to and plays
it back fine. When I press record, the TV/VCR light in the VCR display
indicates VCR. When I set the timer to come on and record, the VCR will
automatically turn on in TV mode and it does not change to VCR mode. The
picture on the TV (while recording) shows the channel which is shown
when the VCR is in TV mode, in my case it shows picture of channel 3.
When I play back this recording, all I get is snow and no sound. So it
seems as though the tuner does not tune when timer recording happens.
When manual recording happens, the tuner tunes in the chosen station
fine.
I have posted a picture of the on screen graphics for my timer settings.
Note that it is set to record channel 11. The record speed is not shown
in the pic because that flashes and the camers snapped the shot when the
speed was not visible. After I set this up, I press "program" button as
per instruction book, then turn VCR off and wait until it automatically
turns on.

I hope this clarifies any confusion that my previous posts may have
caused.
